SPOOL on BOBBIN George B. Markle, Jr., Hazleton, Pa., assignor to Freeland Spool. & Bobbin Corp., Hazleton, Pa., a corporation of Pennsylvania Application March 4, 1946, Serial No. 651,899

This invention pertains to spools or bobbins but more particularly and specifically to a novel and improved construction to facilitate, simplify and improve the manner of driving, that is rotating, spools or bobbins.

The primary object of the invention is accordingly the provision of a spool or bobbin constructed in a manner whereby it can be driven in a novel and improved manner.

By reason of the construction provided for the drive of the spool or bobbin other advantages are obtained, the nature of which will be set forth in the following detailed description of the invention.

One embodiment of the inventive concept is illustrated in the accompanying drawings but departures from the specific construction illustrated therein can be made without departure from the inventive concept, and the drawings are accordingly to be considered as illustrative and not limitative of the invention as the invention is to be limited only within the scope of the hereinafter following and appended claims.

In the drawings:

Figure l is a longitudinal sectional view through a spool or bobbin embodying the inventive concept.

Figure 2 is an end view of an adapter suitable for driving the spool or bobbin.

Figure 3 is a longitudinal sectional view through the adapter illustrated in Figure 2.

Figure 4 is an end view of the spool or bobbin with the adapter therein, a portion of the view being broken away and the spindle being shown in section to better illustrate the invention.

Referring now to the drawings and describing in detail the construction illustrated thereby, A is a hollow thin walled open ended barrel the length of which is optional, but in the present instance is approximately nine inches long. Interiorly the barrel is provided with integral longitudinally extending spaced ribs I, 2 and 3. The thickness, depth, and precise configuration of these ribs is optional as is likewise the number of ribs provided around the interior diameter of the barrel. It is thought that three ribs are fully adequate but a greater number could be provided were it found desirable for any reason.

The spool or bobbin is completed by the provision of a head at each end of the barrel and the particular construction of these heads could and will vary in accordance with the particular use f or which the bobbin is intended.

: In the bobbin embodiment here illustrated there is at one end of the barrel 2. head B and at 4 Claims. (Cl. 24.2-46.3)

the opposite end of the barrel a second head ferential shoulder l3.

which for clarity in description in differentiating it from the head B will be referred to as a knob. The head B at its under side is centrally recessed at 4 to receive the reduced end 5 of the'barrel, which construction provides on the barrel a shoulder 6 against which the under side of the head abuts. The head is provided with a central opening which telescopically receives a ring D which at its outer end is provided with a circumferential flange l abutting and lying against the outer face of the head and is provided with an inwardly extending skirt 8. This skirt extends into the interior of the barrel and to accommodate it the barrel ribs at this end of the barrel stop short of the barrel end, as clearly appears in Figure 1 of the drawings. The ring D and the head B are secured together and are in turn detachably connected to the barrel end by a plurality of screws 9 which pass into and have threaded engagement in the ends of the barrel ribs.

The knob C at the opposite end of the barrel is secured to the barrel by a plurality of screws It] or the like'which have threaded engagement with the opposite ends of the barrel ribs. This knob is provided with a central opening H and clamps between itself and the barrel end an insert or bearing E the interior diameter of which provides a bearing contact with a driving spindle The adapter F is a hollow tubular member having at its outer end a head I2 of greater diameter than the rest of the adapter so as to provide at the under side of the head a circum- Exteriorly the adapter is provided with threecut-out portions I4, l5 and I6 which construction provides on the outer face of the adapter three ribs l1, l8 and IS. The cut out portions are for the reception of the ribs I, 2 and 3 of the bobbin barrel while the ribs ll, [8 and [9 are intended to be disposed in the spaces between the barrel ribs.

It will be understood that the adapter has suitable driving connection with a spindle or shaft G from which it receives rotative motion.

The manner of use and operation of the arrangement is as follows. The diameter of the opening in the ring D is such as to snugly receive the head l2 of the adapter. The adapter is slid through'the ring opening until the shoulder F of the adapter abuts the ends 20- of the barrel ribs. The out out portions [4, l5 and N5 of the adapter receive the ribs l, 2 and 3 of the barrel and the ribs ll, [8 and IQ of the adapter are disposed in the spaces between the barrel ribs. This interiorly of the other end of the barrel, a short tubular adapter having driving connection with the spindle and disposed within the barrel, said adapter exteriorly provided with a plurality of spaced longitudinally extending grooves adapted to interlock with the ribs of the barrel, said adapter having a portion abutting one end of the barrel ribs to limit the inward movement of the adapter, and said adapter being rotatab1y supported in the aperture of the barrel head.
